Question

Write the common difference of A.P :- 4,2,0,-2

Answer 1

Answer:

The common difference is -2.

Step-by-step explanation:

Given:

• $\sf a_1 = 4$
• $\sf a_2 = 2$
• $\sf a_3 = 0$
• $\sf a_4 = -2$

To Find:

• Common difference (d) = ?

Solution:

We know that,

Common difference = $\sf a_2 - a_1$

= 2 - 4

= -2

Also, Common difference = $\sf a_3 - a_2$

= 0 - 2

= -2

Therefore, Common difference is -2.
